CAR-COUPLING. 7

SPECIFICATION forming part of Letters Patent No. 510,949, dated December19, 1893.-

Application tiled August 5,

-.Z0 all whom it any.concern:

Be it known that I, EDWARD W. WooLLEY, aresident of Jersey City, Hudsoncounty, State of New Jersey, have invented an Improved Oar-Coupler, ofwhich the following is a specification.

My invention relates to car-couplers and has for its object to produce asimple, cheap and reliable meansfor automatically coupling the cars of arailway train. I attain these ob- 160118 by the mechanism illustrated inthe accompanying drawings, in which Figure l is a. side view of myimprovement showing the operated parts in dotted lines. Fig. 2 is an endview thereof. Fig. 3 IS a section on line 3-3 of Fig. 2. Fig. 4 is a topView of the coupler showing by dotted lines the position of the couplinglink in the drawhead. Fig. 5 is a detail view of the coupling pin. Fig.6 represents an apparatus for holding the pin in an elevated positionwhen desired. Fig. 7 is a section on line 77 of Fig. 6.

A represents an ordinary form of drawhead for railroad cars, and B astandard link adapted to enter and be secured therein.

0 represents the pin which enters the link in the usual manner tocomplete the coupling. Pivoted at it, in a recess 1) in the drawhead, isa bell-crank 0, one arm of which extends into the recessD in thedrawhead in the path of the link and is slightly rounded. To the otherarm of the bell-crank is pivoted one end of a link d, the other end ofwhich is pivoted in a recess e in the pin 0 and co-operates with thebell-crank to lift the pin. The pin 0 works in a way f extendingvertically through the drawhead. The pin is provided with shoulders ggto act as stops when the pin has been dropped in the way in thedrawhead. A recess h is provided in the pin 0 for the reception of therounded end of the bell-crank lever, and also to fit over and engage theprojection 't' in the Way f, which forms a bearing to prevent lateralplay, and to steady the pin. The pin is slightly hollowed. or notchedtransversely on its rear face as atj, to form a seat forthe link, and toprevent the pin from being lifted by the link in its unavoidablemovement due to the jarring and the sudden variation of tension when1893.

- stopping and starting the train. It willbe seen that the pivot itextends entirely through the drawhead so as to be readily removable,

moved, and the broken or worn out parts replaced. The drawhead may bemade in the usual manner, as by casting. The remaining parts I prefer tomakeby drop forging.

The operation is as follows: The parts are in the dotted line positionof Fig. 1, and a link is approached in the manner shown in full lines insaid figure. This link in the act of coupling is fast in the coupler ofanother car. The link is thrust into the recess D and strikes againstand rocks the bell-crank lever. This by means of the link (1, lifts thepin 0 to clear the link B in its entry. (See Fig. 2.) As the link ispressed home the bell-crank lever falls into the aperture in the linkand allows the pin 0 to also fall into the same aperture, and preventthe link from being withdrawn from the .drawhead. The parts are nowagain in the position shown in dotted lines in Fig.1. To nncouple, thepin may be lifted in any suitable manner, as by engaging the eyel withsome such device as is represented in Figs. 6 and 7, and the linkwithdrawn from the drawhead. When the pin has been lifted high enough toclear the link, the rounded end of the bell-crank will enter the recessh in the pin and be thereby protected from injury as the link iswithdrawn.

As it is often desired to hold the pin in an elevated position to holdthe parts out of operation, I have shown a device for the purpose inFigs. 6 and '7. The rod 0 is mounted in brackets q on the end of a car,and has fast thereon a sheave s over which passesa chain or cord mattached to the eye 1 of the pin. Handles r on the rod 0 serve to rotateitto wind the chain and lift the pin. hen it is desired to hold the pinin an elevated position after it has been raised, the rod 0 is slidlongitudinally in the brackets in either direction and the pin p and camstops it on the rod and bracket respectively come in contact and formstops to prevent the further rotation of the rod. When it is desired tolower the pin from this fixed position, the operation is reversed.

Having described my invention,1 claim- 1. In a car-coupler, thecombination with a in order that the working parts may be re- IOCdrawhead, of a bell-crank pivoted thereto,

having one arm extending into the path of a coupling link and adapted tobe struck 'thereby, a pin for securing the coupling link'in thedrawhead, and a link pivoted to the pin and to the other arm of thebell-crank, substantially as described.

2. In a car-coupler, the combination with a drawhead, of a bell-crankpivoted thereto, having one armextending into the path of a couplinglink and adapted to be struck thereby, a pin for securing the couplinglink in the drawhead,and a link connection between the pin and the otherarm of the bell-crank pivoted in a recess in the pin, substantially asdescribed.

3. In a car-coupling, the combination of a bell-crank c, pivoted in arecess 1) in the drawhead and having one'arm extending into the ated byone arm of said bell-crank, and hav- I ing therein a recess forreceiving the end of the other arm of the bell-crank,substantially asdescribed,
